A medical researcher wishes to try three different techniques to lower blood pressure of patients with high blood pressure. The subjects are randomly selected and assigned to one of three groups. Group 1 is given
Medication, Group 2 is given an exercise program, and Group 3 is assigned a diet program. At the end of six
Weeks, each subjectʹs blood pressure is recorded. Find the critical value $$\mathrm { F } _ { 0 }$$ to test the claim that there is no
Difference among the means. Use $$\alpha$$ = 0.05. $$\begin{array} { c c c }
\hline \text { Group 1 } & \text { Group 2 } & \text { Group 3 } \
\hline 9 & 8 & 4 \

11 & 3 & 4 \
15 & 5 & 8 \
13 & 4 & 9 \
